To quote one of my favorite bloggers (because she captured what I thought perfectly):
Finn, after having been on an uncertain path for the future, declares to Mr. Schue that he wants to join the army, just like his dad. He's translated his original Glee speak of wanting to be a part of something special to being a part of the army, and honoring his deceased father's legacy. And frankly, I'm on board with a storyline where Finn can attempt to connect with his father and let go of some of his angst over manhood.
It turns out though, as Carole revealed to Finn, that Finn's father did not die an American hero in Iraq. Rather, he was discharged honorably, and suffered a drug problem when he returned home. After disappearing one night, he turned up dead in Cincinnati from an overdose. Pretty shocking, right? It rightfully turned Finn's world upside down and he was forced to deal.
I didn't like that so much of Finn's angst was framed solely in the discussion of what it means to be a man. Really, Glee? Are we still on this? Usually, it's done interestingly with the inclusion of Kurt, or another gay male character to introduce the question naturally and with thought-provoking results. (Because frankly, the answers to that question are pretty limiting, insulting to both genders, and, if you'll excuse me, complete bullshit.) But this time, neither Kurt nor Blaine were on the scene, and we instead got Will telling Finn he taught him how to be a man, and Finn questioning what kind of man he was after learning the truth about his dad. It also bears stating that Finn has previously told Will that he taught him how to be a man in the absence of his father, and that he also told Kurt that he taught him how to be a man. At this point, it's becoming a worn-thin plot device that isn't even progressing these characters in any real way.
Ultimately, Finn's crisis manifested in a lot of talk about not knowing what kind of man he was, and then channeling that somehow into feeling like he'd be okay if he just proposed to Rachel so he could love her forever. That doesn't really connect. It would have been stronger to see Finn have an actual emotional response independent of gender-centric bullshit, and allow him to work through his issues with his mother, who, may I remind everyone, also gave 50% of her genes to her kid. It would have been a better choice to see Finn be reassured that just because his father had struggles didn't mean that he was doomed to the same fate, and that he can look up to his strong, hardworking single mother just as much as his absent dad. It would be far less sexist, and give Carole Hudson a little more credit as a single woman trying to raise her son in Middle America. Not only that, but it would have been nice to get more sympathy for Finn's dad - it immediately crossed my mind that his drug issues could easily be connected to the emotional toll of fighting a war and returning home from it, which is far more three-dimensional and nuanced for Finn to deal with, rather than "my dad was a loser and I'm destined to be one too."
